[Mel Feliciano]"What you and I want to know is if there is going to be any conflict with Premiere Pro not recognizing the quadro 4000 card because of the GT-120"

As I responded to Jose, the answer is yes. Premiere as of CS5.5 can only use the card the display is connected to for MPE. Resolve, can't use the card the display is connected to for processing. So you're damned if you do and damned if you don't.

The best solution is as Sascha proposed. Y-split for power, and a GTX470 + Quadro 4000, this would allow you to hve the quadro for MPE connected to monitor & the 470 unconnected to any display for DaVinci.
